Oxygen content-controlled high-flow velocity multi-state aqueous corrosion experiment apparatus

Abstract

The invention belongs to the technical field of a corrosion experiment apparatus, and discloses an oxygen content-controlled high-flow velocity multi-state aqueous corrosion experiment apparatus. Theoxygen content-controlled high-flow velocity multi-state aqueous corrosion experiment apparatus comprises a water supply system, an oxygen-controlled system, a hydrochemical survey system, a loop pipeline, a heating insulation system, a heat exchange system, a sample chamber, a back-pressure valve, a filter, and a control cabinet; and an experiment sample is placed in a sample chamber. The oxygencontent-controlled high-flow velocity multi-state aqueous corrosion experiment apparatus can simulate different media environments under a plurality of experiment parameters, and provides different temperatures (less than 700 DEG C), pressure (less than 30 MPa), flow velocity (less than 3m/s), supercritical water (less than 10m/s), and superheated water vapour (less than 40 m/s); can simulate service environment of a light-water reactor nuclear power station, service environment of a supercritical water reactor and supercritical thermal power, and superheated steam environment in thermal power, and reduces N2 consumption; and can heat rapidly flowed medium.

Description

technical field [0001] The invention belongs to the technical field of corrosion experiment devices, and in particular relates to a high-flow rate multi-state water corrosion experiment device for controlling oxygen content. Background technique [0002] Materials face serious corrosion problems in the environment of high temperature and high pressure water, represented by the corrosion of high temperature and high pressure water, supercritical water and superheated steam (280 ° C ~ 600 ° C, 8 ~ 30 MPa) in the field of nuclear power and thermal power. Steam circulation components such as superheaters, reheaters, high-temperature steam pipes, turbine rotors, blades, and nozzles in thermal power plants are corroded by high-temperature and high-pressure steam; pressure components in nuclear power plants such as pressure vessels, steam generators, return pipelines, and heat exchangers Corrosion by high temperature and high pressure water; and related components in supercritical ...
